Short description
Bestämningsnycklar | Morfologi | Morfometri
Ryggkotor: 98 - 99. Pelvic fins small (Ref. 4695). Dark, with 5-8 short, light cross-bands on back and dorsal fins; light band (or spots) at nape; transverse light bands on body, never becoming a network in older fishes (Ref. 4695).
Found on muddy bottoms (Ref. 4695). Benthic (Ref. 58426). Smaller individuals prey on smaller species like amphipods, isopods and small bivalves while larger ones prey on shrimps, euphausiids and fish (Ref. 13532).
